Public preview: Azure Availability Zones
Published date: 14 October, 2017
Azure Availability Zones are now available for preview in two regions, US East 2 and West Europe. The current list of enabled regions and services is available on the documentation page.
Availability Zones are fault-isolated locations within an Azure region, designed with independent power, cooling, and networking. They help protect your mission-critical applications from failures of entire datacenters with low latency and high availability.
We offer a single-instance VM SLA of 99.9% on VMs backed by Azure Premium Storage, and we offer a 99.95% SLA for availability sets.
To get started with Azure Availability Zones, go to the Azure portal and enable your subscriptions for preview.
